Now that preorders have begun for Apple’s iPhone XS and XS Max, wireless carriers are offering deals on the new devices. We’re rounding up where to get the best discounts, including buy one, get one $700 off promotions.

AT&T Wireless

Kicking off our wireless deal roundup is AT&T Wireless. The wireless giant has added Apple’s iPhone XS and XS Max to its popular “buy one, give one” program, which provides shoppers with $700 off when two qualifying devices are purchased. The promotion requires users to buy both devices on AT&T Next with a minimum wireless plan of $65 per month (combined) after the discount. It also requires a new line in order to secure up to $700 off in credits over 30 months. As with other wireless deals, if service is canceled, the device balance becomes due. An activation fee of $30 does apply.

Find out how to take advantage of the deal by visiting AT&T Wireless’ website.

Verizon Wireless

Like AT&T, Verizon Wireless is running its own buy one, get one $700 off promotion. Shoppers can mix and match any two iPhone XS Max, XS, X, 8 Plus or 8 256GB devices, and you will need to add a new line to one of the phones. You’ll then see a credit of $29.16 per month over 24 months on your bill.

If you do not wish to add a line and have an old device lying around, you can instead take advantage of Verizon’s $100 trade-in deal with the iPhone XS or XS Max. To qualify, you must have a qualifying trade-in that’s in good working and cosmetic condition. You’ll then see $100 over 24 months as a small monthly credit starting in one to two billing cycles. This ends when the balance is fully paid, or if you cancel or transfer your line to another plan. Luckily, if the market value of your trade-in is higher than $100, you’ll get the full value as an account credit in one to two billing cycles.
